Therma-Tru Roof Repair in Miami: What to Know First
Therma-Tru roof repair in Miami means repairing or replacing the roof components on Therma-Tru entry doors, storm doors, sidelights, and transoms. Most jobs we handle are completed in a single visit, and our pricing runs honest and upfront: you’ll know the number before we touch anything. As an independent Therma-Tru service provider, we are not a manufacturer warranty station, but we fix Therma-Tru door roofs correctly and stand behind the work for 90 days.

This page is for Miami homeowners whose Therma-Tru door roof leaks, sags, or has pulled away from the wall. If you’re calling because water is coming in around the top of your entry door after rain, you’re in the right place. Call (561) 489-4036 and a live person answers, day or night.
How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru builds a good door, but Miami’s sun and salt air find the weak points over time. Here’s what we see most often on roof repairs in this market:
- Ultra-Series cap rot at the seam. Therma-Tru’s Ultra and Traditional lines use a PVC cap over a composite core. On older Miami installs, the cap’s top seam splits after years of thermal cycling, letting water sit against the core. We repair or replace the cap and reseal the seam with a marine-grade sealant rated for constant UV exposure, not the standard silicone that bakes out in two summers.
- Sidelight roof flashing pulled loose in Brickell and Coral Gables. High-rise wind funnels along Brickell Avenue hammer entryways with gusts that lift cheap flashing. We see this constantly on Therma-Tru Systems sidelight assemblies. The fix is real roof flashing tucked under the wall’s weather barrier, not surface caulk. We reflash the full head assembly and lap it so water sheds outward.
- Transom rot on Smooth-Star units. Therma-Tru’s Smooth-Star line has a fiberglass skin, and when the upper transom is site-built on a wood buck without proper slope, Miami’s afternoon downpours collect at the joint. We set the transom with positive drainage slope and rebuild the rough opening flashing before reinstalling any frame member.
- Door roof overhang sag from failed header shims. On fiberglass door installations from the early 2000s, contractors sometimes used untreated wood shims under the frame header. Once those shims compress or rot, the entire door roof drops and binds the door panel at the top. We replace shims with composite horseshoe shims and reset the frame level.
- Storm door roof assembly shaking loose on Pulse line installs. Therma-Tru’s Pulse storm doors get rattled by Miami’s daily thermal expansion and the occasional tropical storm. The roof receiver channel backs out its fasteners. We through-bolt the receiver into the king stud instead of relying on the original short sheet-metal screws.
Our Therma-Tru Roof Repair Process
Here is what a Therma-Tru roof repair with TruePane Windows & Doors looks like from call to cleanup:
- 1
You call (561) 489-4036. A live person answers and schedules a time that works. No hold music, no callback later.
- 2
We inspect the entire door head. We look at the cap, flashing, shims, transom slope, and the weather seal. We measure the rough opening twice before ordering anything. Dale Kessler taught us that reading the opening first saves everyone money.
- 3
We price it in writing. You see a line-item quote on paper before any work starts. No surprise additions on the final bill.
- 4
Parts decision. We use Therma-Tru OEM parts when the component is structural or warranty-sensitive. For sealants and flashing, we use higher-quality aftermarket materials that outperform the factory spec in Miami’s climate.
- 5
The repair. Uniformed, background-checked technicians do the work with a drop cloth down and the work area cleaned before we leave.
- 6
We test and document. Water testing at the head, a level check on the frame, and photos of everything we touched. Then we register the work under our 90-Day Done Right Promise.
What Therma-Tru Roof Repair Costs in Miami
Therma-Tru roof repair costs in Miami span a realistic range depending on what failed. Here are the numbers we quote most often:
- Header flashing replacement: $280 to $540
- Cap or roof trim repair on a single door: $180 to $320
- Sidelight or transom reflash and reseal: $420 to $780
- Frame header reset with new composite shims: $350 to $650
- Full door head rebuild with transom slope correction: $900 to $1,600
What moves the price is access, the condition of the existing rough opening, and whether water damage spread past the door frame into the wall cavity. We inspect before we quote, so the number we give you is the number you pay. Call (561) 489-4036 for a free estimate.

Why Miami Homeowners Call TruePane Windows & Doors for Therma-Tru Work
We have served South Florida homeowners for over 42 years through a second-generation glazier’s craft tradition. Dale Kessler started TruePane Windows & Doors in 2008 with one rule on the whiteboard: if the pane is not true, the job is not done. That applies to door roofs the same as it applies to glass.
Our technicians know Therma-Tru’s lines well enough to order the right part the first time, and when a repair isn’t worth doing, we’ll tell you straight and quote you a replacement. We’re also authorized installers for PGT, CGI, CWS, and ES Windows, so if your Therma-Tru door has reached the end of its service life, we can show you Miami-rated hurricane alternatives side by side on paper. Every job is covered by our 90-Day Done Right Promise and The Keystone Standard: both warranty layers registered in writing, durations stated, before we leave your driveway. No arguing, no fine print games. A live person answers our phone 24/7. Call (561) 489-4036 and you’ll get a real voice, not a tree.
FAQs
In most cases, yes. We use Therma-Tru OEM parts for structural components and document the repair. As an independent Therma-Tru service provider, we cannot process manufacturer warranty claims, but our repairs are done to spec with materials that meet or exceed factory requirements. If you have an active Therma-Tru warranty, call (561) 489-4036 and we’ll walk you through the language in your paperwork before any work begins.
Most Therma-Tru roof repairs are completed in a single visit lasting two to four hours. Repairs that require rebuilding a transom or replacing a rotted header may take a second day. We tell you the timeline before we start and we’ll be there when we say.
If the door panel and frame are sound and the roof failure is isolated to flashing or cap components, repair makes sense and costs far less. If the composite core has absorbed water over multiple Miami wet seasons or the frame is twisted, replacement is cheaper long-term. We’ll show you both options with real prices on paper. Call (561) 489-4036 for an honest assessment.
Both, depending on the component. Structural parts like caps, astragals, and receiver channels are OEM Therma-Tru, same as the factory specked them. Sealants, flashing, and fasteners are higher-grade aftermarket products chosen specifically for Miami’s salt air and UV exposure. We explain every part choice on your written quote before the work starts.
Most Therma-Tru roof repairs are considered maintenance and do not require permits in Miami. If your repair involves structural header replacement or exceeds the scope of maintenance work, we tell you upfront and handle the permitting process. You will never find out about a permit issue after the work is done. Call (561) 489-4036 and we’ll tell you what your specific job needs.
